Difference between 3D modeling and rendering

Nowadays it is not surprising to hear a variety of synonyms describing one object or process. The technological development has also resulted in the appearance of new vocabulary that can seem odd to somebody. No wonder only some individuals recognize the difference between software and tools, CPU and GPU etc. With the introduction of 3D technology, the number of terms connected with it has also multiplied by several times. One pair of notions that causes some misconceptions among users is also connected with 3D. Many modern companies offer 3D rendering and 3D modeling services, but unfortunately, not every client fully realizes what he will finally acquire ordering ones or other services. In this article, we would try to explain how these terms differ from each other and what is common among them too.

Defining 3D modeling and rendering

Difference between 3D modeling

Every specialist who deals with 3D technology has to complete a certain number of stages that constitute the workflow. Modeling and rendering are two important stages of 3D workflow next to simulation, animation, visualization etc. At the same time, these are two most important processes that can not be performed without each other.

Modeling is a development process of the mathematical representation of the object or living being. It is a process of building, constructing, connecting pieces. Modeling reminds a work of a sculptor or carpenter who uses GPU as the main tool for creating his masterpiece.

Rendering is the process of turning a model into an image, video or animation, providing it with new effects and placing it into the realistic setting. It is like the work of a photographer who creates a perfect background for the model he shoots.

Being the stages of one 3D workflow, these processes are connected between each other, but still, have absolutely different purposes. Modeling is one of the initial stages of the visualization process. You need to create the main ‘hero’ of your final project with the consideration of the smallest details. It is the act of making a model that would be subjected to different effects during the rendering process. The last one is regarded to be one of the final stages of the workflow. It includes adding such effects as lighting, orientation, backgrounds, animations etc. The main goal of the renderer is to transform virtual bits into a photorealistic output in different forms (images, videos, animations etc.). One more difference between these two notions are purposes set for them. 3D modeling is used for:

  • Enabling improved project planning;
  • Showing any exist in interferences among building systems;
  • Visualizing a schematic structure of the future object;
  • Eliminating conflicts before system installation.

The main goals of 3D rendering are more general:

  • Enabling improved design-related decisions;
  • Facilitating marketing, presentation and design analysis;
  • Displaying ideas in various forms.

Both these processes depend on each other. There is no sense in creating a background if you do not have a focal point of your project – the main one or several models. Vice versa, the model looks raw and unfinished without a quality rendering process, so both these notions are interdependent. However, when you turn to the company in search of quality 3D services, you need to understand if you need a fully developed project with rendering or just a creation of the model that will be used further for other purposes.

Furniture Photography VS Product Rendering
